Large quantity of data will be missing when snmptest.pl is used. The reason
is a sort in lexicographic order:
$ snmpwalk -v2c -c public localhost .1.3.6.1.4.1.2021.250.255 |head
iso.3.6.1.4.1.2021.250.255.2.1 = STRING: "10.4.52.1"
iso.3.6.1.4.1.2021.250.255.2.10 = STRING: "192.168.35.64"
iso.3.6.1.4.1.2021.250.255.2.100 = STRING: "192.168.196.1"
iso.3.6.1.4.1.2021.250.255.2.101 = STRING: "192.168.198.1"
iso.3.6.1.4.1.2021.250.255.2.102 = STRING: "192.168.209.225"
iso.3.6.1.4.1.2021.250.255.2.103 = STRING: "192.168.209.241"
SNMPGetNext after "root.2.1" should give "root.2.2". Thus, lots of
variables are missing.
The function is now dependant on a CPAN module NetSNMP::OID, (debian/ubuntu
package is called libsnmp-perl). This is probably not the most efficient
way to do it: walking the whole tree will be much slower.
